Rezolva in R ecuatia 1) 8x - 1 supra 5 - 1 = 50 - 2x supra 9 + 3x + 3 supra 4

Answer 1

1)8x-1/5-1=50-2x/9+3x+3/4
8x-1-5/5=200-8x+108x+27/36
8x-6/5=100x+227/36⇒.
36(8x-6)=5(100+227)⇒
228x-216=500x+1135⇒
228x-500x=216+1165⇒
-272x=1351⇒
x=1351/-272

2)3y+1/3-16-y/6-9y+1/7=3⇒
42y+14-672-7y-378y+6/42=3⇒
-343-652/42=3⇒
-343y-652=126⇒
-343y=652+126⇒
-343y=778⇒
y=778/-343
